This is a fantastic product at any price, but especially amazing considering the low cost as compared to other similar functioning pdf editors. The interface is clean, pretty and easy to use. It is extremely intuitive and has virtually no learning curve. It fit a very specific niche for me (I needed a fully functional pdf editor that could operate without limitations within an Internet Explorer extension) and did so brilliantly, but even as a stand alone product it is head and shoulders above the rest (and I tried them all). I am particularly impressed with the thoughtfulness that is evident in the design of the interface. Even Acrobat is not as well thought out or intuitive. To put it simply, it just works! I have put it through it’s paces and nothing, including Acrobat Pro DC, can keep up and do what I needed to do. I cannot remember being this satisfied with a software purchase in my life (no hyperbole). I am work in health care and I could only wish that any of the EMR applications I’ve had to work with over the years was as well-programmed, thoughtful and intuitive and this powerful little product. Job very well done!
